BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to a method of continuously mixing and tempering a resin compound, especially, a method of applying plural kinds of raw materials quantitatively into a mixing-tempering machine.
2. Description of the Related Art
In a process of continuously mixing and tempering raw materials, a measuring apparatus by volumetric method or a measuring apparatus by weighing method is used for measuring and applying the raw materials. According to the measuring apparatus by volumetric method, a process includes the steps of rotating a screw-feeder in a low speed, measuring materials with a predetermined volume thereby, and applying the measured materials into a mixing-tempering machine. According to the measuring apparatus by weighing method, a process includes the steps of detecting a supplying weight of the raw material by a load cell, controlling a motor for applying the detected raw materials by informing the supplying weight of the raw materials, and applying the raw materials with a predetermined weight into a mixing-tempering machine (refer Japan Patent Published Application No. H06-71640).
SUMMARY OF THE INVENTION Objects to be SolvedAccording to the measuring apparatus by volumetric method, since the measuring the raw materials is controlled by a volume of the raw material, measuring accuracy is depended on an apparent specific gravity, so that it causes that manufacturing may have difficulties in control (it means that feed-back control could not follows changes: when various materials with different specific gravity, controlling a rotating speed is acted frequently by the feed-back so that the controlling could not follows the changes).
According to the measuring apparatus by weighing method, since the load cell is generally fragile against a shock from outside, measuring accuracy is influenced by a shock by applying materials or by acting a material feeder, so that it causes that quality of a resin compound would be unstable (a vibration caused by biting the raw materials is generated by rotation or vibration when feeding raw materials).
How to Attain the Object of the Present InventionAccording to the above problems, an object of the present invention is to provide a method of applying raw materials, which can make manufacturing easy in control and stabilize quality of compounds.
In order to overcome the above problems and attain the object of the present invention, a method of applying raw materials according to the present invention is characterized of including the steps of preparing a pack of each of the raw materials with each determinate quantity in a packed form by measuring each of the raw materials and packing it respectively with the each determinate quantity in preparing processes; and applying each required number of the packs of each of the raw materials with the each determinate quantity prepared in the packed form to the mixing-tempering machine.
In order to overcome the above problems, a further method of applying raw materials according to the present invention is characterized of including the steps of preparing a pack of a blended material with a determinate quantity in a packed form by measuring each of the raw materials and blending measured materials and packing the blended material with the determinate quantity in preparing processes; and applying required number of the packs of the blended material prepared in the packed form to the mixing-tempering machine.
According to the present invention having the above features, the raw materials can be applied quantitatively into the mixing-tempering machine. The compounds to be used, which is given by applying the raw materials quantitatively and mixing and tempering it, can be stable in quality.
Effects of the InventionAccording to the method of applying the raw materials of the present invention, manufacturing it can be controlled easer than usual, and quality of the compounds can be stabilized more than usual.
The above and other objects and features of this invention will become more apparent from the following description taken in conjunction with the accompanying drawings.
With reference to figures, a method of applying raw materials according to the present invention will be described.
